IMPROVEMENT IN PACKAGES FOR ALKALIES, ACIDS, 84e.

Specification forming part of Letters Patent No. 124,859, dated March19, 1872.

To all whom it may concern: g

Be it known that I, JACOB H. SEIBERT, of

of Pennsylvania, have invented a new and useful Improvement in Methodand Package for Putting up' Caustic Alkalies, Acids, Salts, and otherChemicals, of which the following is a My invention relates to packagesfor putting up caustic alkalies, acids, and other articles of acorroding or deliquescent nature, and which it consists, first, of amold of 'tapering form, cast or provided with a base-ring or surroundingcollar, whereby provision is made for the cutting of a recess for thereception of the head,

purpose of hermewtwically sealing the package, the slightly-taperinginold enabling the operator to form the sides and bottom at oneand thesame operation, whereby a stronger and more perfect package is secured;second, :in the manner of constructing the package so that the sides andbottom thereof are formed at one and the same operation.

In the drawing, Figure l represents a vertical central section of themold or former and the ring or collar. Fig. 2 is a vertical section ofthe package, mold, and collar, showing the sides and bottom of thepackage. Fig. 3 is a section of the package, showing the recess for thereception of the head, the mold and collar having been withdrawn. Fig. 4is a section of the package when complete.

Like letters refer to like part-s in the several A is thc mold orformer. It may be of any shape desired, provided, always, that it taperslightly from the base to the top, so that its diameter shallbe'slightly less at the part lettered a than at the bottom or partlettered b. The tapering form is necessary to enable the mold to bewithdrawn `after the package is formed. The mold is of metal or othersuitable material, and is formed hollow, constituting a cup, for reasonshereinafter explained., B is a collar, ring, or surrounding frame.Accordin g as the base of the mold is square, oblong, or cylindrical, sowill be the shape of this part ofthe apparatus. This collar correspondspackage, and in height to the thickness of the head. The collar maybemade of the same material as the mold, and will, in some instances, beformed solid with the mold. v C. is the outer covering of the package,and consists of paper, pasteboard, or other suitable material or fabric.The wrapper C rises above the mold for a distance equal to the thicknessof the wall ofthe package. E is the intermediate or plastic mass whichconstitutes the package proper. This plastic material may be made invarious ways and of various materials, provided, al-

ways, that the requisites of lightness, strength,"`

and impermeability be obtained. I prefer to make it of glycerine, wax,and paper-pulp. The wax is melted, a small quantity of glycerine added,and the paper pulp intimately worked in until a plastic mass of theproper consistency is formed. -If parafiine is added a small quantity ofwax will be required.

To constructthe package, themoldAis placed upon a table or othersuitable bed,with the col- "lar B at its base occupying the positionshown in Fig. 1 of the drawing. A sheet of paper,

pasteboard, or muslin, C, is then folded around the collar I3, wrappedor made in the form of a collar and placed upon the collar B, so as toform an intermediate chamber between the paper and the mold. In someinstances I willA cover the outside and bottom of the mold with atight-fitting protecting wrapper of paper, wood, muslin, or othermaterial, or asbestus may be applied directly and produce a good result.This space is lled with the plastic mass E, composed of glycerine, wax,and pulp or other suitable material, and the mass can be pressed orpacked to a uniform density, if desired. As the paper or wrapper G risesabove the mold for a distance equal to the thickness of the Walls of thepackage, all that is necessary to form the bottom ofthe package is tofill the wrapper, completely covering in the mold. When the sides andbottom of the paclr age have thus been formed, and the bottom hasreceived its covering of muslin, paper, or other material, the packageis lifted oft' the mold, which is easily accomplished owing to thetaperingform of the mold. The package is now coated upon its interiorsurface with one or more layers composed of a solution of resin,sealing-wax, or other suitable material, and is ready for the receptionof its charge.

Heretofore, in lling packages with caustic alkalies, te., the hot liquidhas been poured into the package and allowed to set therein. This I iindis detrimental to the package, renderingunserviceahlemanypackagesthatwould otherwise fulll all the requirements of a secure wrapping orcarrieln To avoid this, I have formed the mold or former A hollow, sothat each mold will serve as a condenser in which to cast and con gealthe alkali previous to transferrin g it to the package of correspon dingsize.

The mold A, being set upon its smaller end, is filled with the causticalkali, which rapidly cools, and is then transferred to one of thepackages formed as above described. Over the upper surface of the alkalicontained in the package a thin piece of paper or other suitablematerial is laid and the space corresponding to F, Fig. 4, is lled withthe plastic mass above described. This head hermeticalbT seals thepackage, and the article is complete.

- It is obvious from what has been said above that this package isadapted for putting up gunpowder and various other articles whichrequire a secure Water-proof or re-proof wrap ping; and it is alsoobvious that instead of using the mold A as a condenser and congealer, aseparate vessel mi ght be employed to perform that function.

The packages can be made of such sizes as the market demands.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-f l. A tapering mold, A, provided with acol lar, B, for the purpose of casting a plastic mass upon an outsideprotecting wrapper for foriniug the bottom and sides of packages forcontaining caustic alkalies, acids, salts, or other chemicals.

2. A package for alkalies, acids, salts, or other chemicals, constructedso that the sides and bottom thereof are formed at one and the sameoperation by casting a plastic mass upon a protecting wrapper.

3. A package for caustic alkalies, acids, salts,

or other chemicals formed by casting a plastic substance between aninside and outside protecting Wrapper, as specified.

To the above I have signed my name this 14th day of February, A. D.1872.
